QW Monitors Specifications (pdf)

The QW monitor is a two-way, full-range floor monitor loudspeaker system employing a newly-developed Pro Rider 15" woofer along with a 44XT compression driver and a CH®-6 conical constant directivity horn.

The QW monitor’s shape helps reduce the build-up of standing waves inside the enclosure, which minimizes mid-bass and mid-range coloration. It is constructed of premium 18mm poplar plywood and is covered with a tough, durable, black textured Hammer Head polyurethane coating. A 16-gauge, powder-coated, perforated metal grille covers the front of the system to protect the speakers from external damage.

The 15" Pro Rider woofer features a Kevlar® impregnated, water-resistant treated cone and dust cap for superior environmental stability. A 44XT 4" titanium diaphragm compression driver handles the high frequencies and features the Radialinear Planar Phase Correction System (US Patent 6,064,745), which provides smoother and extended high frequency response. Its CH-6 conical constant directivity horn provides an even 60° coverage in all directions.

Full range input to the system is made via two four-pin Neutrik jacks in parallel. A secondary input location is provided so that either side of the unit may be connected to the amplifier or another monitor used in parallel. A four-pin Neutrik switching jack is provided for biamp input flexibility while maintaining superior signal integrity. The inclusion of a standard four-pin Neutrik jack in parallel on the driver side of the biamp switching jack provides for daisy chaining to another cabinet when biamp operation is desired.

The internal passive crossover features the Sound Guard 44 high frequency driver protection circuit and an advanced topology crossover with high performance components to provide high power handling and reliability. This proprietary, high frequency driver protection circuitry provides long- and medium-term driver overload protection without impairing musical transients or dynamics. The crossover provides driver roll-off and protection as well as driver EQ for the woofer and horn. The result is a clean, clear and smooth response. High quality, reliable crossover components include polypropylene capacitors and high-current inductors. The optimal integration of the crossover with the selected drivers results in a smooth frequency response from the QW monitor.
